I'm 19 years old. And I have started watching anime since the middle point of 7th grade. 13 Years old.
To calculate the amount of animes Iv'e watched per year, In 2008, Iv'e watched approximately 403 animes per year.

Have been addicted for about 3 years.
Have seen about 650 Anime,
Total of series re-watches (counting different times re-watching the same one. Example: Yuru Yuri both seasons about 10 times each) is hmm,,,I'd say around 100. (I know my re-watch count isn't less than a 100, but don't know how much exactly.)

As for Manga and Light Novels have only been hooked for about half a year, so have only completed about 40 manga, currently reading about 100. (this time not throwing the number around, but it's actually around 100.) Have read about 200 Yuri Doujins, which most would count as one-shots.
